forth in the following specification, reference being had to theaccompanying drawing, in which- Figure 1 represents a front elevation ofa machine embracing my invention. Fig. 2 is a vertical cross-sectionthereof in the line as m, Fig. 1. Fig. 3 is a plan or top view of thesame. Fig. 4 is a horizontal section thereof in the line y y, Fig. 1.Fig. 5 is a top view of one of the covering-disks, on a larger scalethan in the previous figures. Fig. 6 is a side view of the laying-head.Fig. 7 is a vertical section thereof.

Similar letters indicate corresponding parts.

This invention relates to that class of machines designed for coveringtwisted strands of threads for the manufacture of cords, and which, forthis purpose, employ a series of spools for carrying the thread to betwisted; an upper series of spools, which carry the covering-thread, andwind it over the twisted threads from the lower spools; and an upperwinding-spool, mounted in a revolving frame, for winding up the cord asit is covered.

My invention consists in the combination, with the two spools whichcarry the strands to be covered, two rotary disks for supporting thespools which carry the coveringthreads, and with the upper windingmechanism, of a revolving friction roller, around which the covered cordpasses prior to being acted on by the winding mechanism, as will be morefully hereinafter set forth.

The invention further consists in a peculiar construction of eyes,through which the strands pass onto the cord to be covered, as will behereinafter set forth, and pointed out in the claims.

In the drawing, the letters A B designate the two spools carrying thecotton or other strands to be covered on my machine. These spools aremounted on spindles G D, which receive a revolving motion from avertical shaft, E, through cog-wheels a b c d, the spindles O D carryingalso guides F, through which said strands pass as they are unwound fromthe spools. With each of the Sp ols A B is combined a brake, G, toprevent the same from moving at a greater rate than the spindles.

Theletters H Idesignate two covering-disks, which receive the strandsfrom the spools A B. These disks are mounted on tubular spindles 6, (seeFig. 2,) through which the strands pass, and they receive a rotary-motion from the vertical shaft E, through gear-wheels f g h c. From theupper surface of said disks H I project a series of pins, j k, forsupporting the spools containing silk or other coveringthreads, and tothe middle portion of the disks is secured a frame, J, to which, inturn, is secured a laying-head, K, (best seen in Fig. 7.) This head Khas a central eye, I, and carries a series of guides, L, which havesuitable eyes for the passage of the covering-threads, and, beingslotted, are secured to the head K by set-screws m passing through theirslots, so that they are adjustable.

The cores or uncovered strands pass upward through the eye I in the headK, while the covering-threads pass from their spools through the guidesL, and are twisted around said strands at a point immediately above thehead. By making the guides L adjustable I am enabled to apply thecovering-threads to the strands with uniformity, or, in other words, Ithereby obviate the liability of their being wound on top of each other.

The covered strands are conducted from the head K over a friction-roller, N, which receives a revolving motion from the vertical shaft E bymeans of a worm and worm-wheel, n o, and thence are wound on a spool, O.I mount this spool on a shaft, 19, to which a revolving motion isimparted by means of a worm, q, and worm-wheel 1, said worm beingsecured to a spindle, P, which is mounted in a revolving frame, Q, andto which is secured a cogwheel, 8, meshing with a stationary cog-wheel,t. To the frame Q is secured a cog-wheel, a,

.while both the frame and this wheel are mounted on a fixed spindle, It,to which the stationary wheel 25 is secured. The'cog-wheel u of therevolving frame meshes with a wheel,

'0, which, in turn, meshes with a wheel, w, se cured to the verticalshaft E. Hence, when motion is given to the shaft E, the frame Q, andwith it the spool, is revolved, while at the same time said spool isslowly revolved on its own axis. The two covered strands which areconducted to the spool O, as stated, are thus twisted together to form acord and wound on said spool at one and the same time.

Between the spool O and its shaft 19 I interpose springs 2, Fig. 1, sothat the spool is susceptible of yielding to any strain to which thestrands wound thereon may be subjected.

It may be remarked that a greater number than two of the covering-disksand their con comitant parts can be used without departure fi'om myinvention.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the two spools for carrying the strands to becovered, the two rotary disks adapted to support a series of spoolscontaining the covering-threads, and the upper winding mechanism, of thefrictionroller N and mechanism for revolving the same, around whichroller the covered cord passes prior to being acted on by the windingmechanism, substantially as and for the purpose described.

2. The combination, with the disks adapted to carry the spoolscontaining the coveringstrands, of the central laying-head K and itsseries of guides L, having eyes, said guides being adjustably connectedwith the layinghead, substantially as and for the purpose described.

In testimony that I claim "the foregoing I have hereunto set my hand andseal.
